Alternative View
Authors who claim that sunscreen use causes melanoma have speculated that this occurs by one of the following mechanisms:
- the absence of UVA filters combined with a longer exposure time of the sunscreen user
- By reducing the exposure of the skin to UVB radiation, sunscreen suppresses the skin's production of the natural photoprotectant, melanin, and the lack of melanin leads to an increased risk of melanoma.
- free radical generation by sunscreen chemicals that have penetrated into the skin.
- pathogenic cytotoxicity and carcinogenicity of micronized titanium or zinc oxide nanoparticles.
- Retinyl palmitate, a form of Vitamin A that is an ingredient in some sunscreens, may encourage tumor growth in animals
